Caliso 22045 Heavy Duty Thermal Engine Cooling Fan Clutch

The Caliso 22045 is a heavy-duty thermal engine cooling fan clutch engineered to meet or exceed original equipment (OE) specifications. Featuring a CNC-machined aluminum body, this bolt-on fan clutch delivers reliable, temperature-responsive cooling performance for a wide range of domestic GM, Chrysler, Dodge, and Plymouth car and truck applications.

This thermal fan clutch uses a bi-metal thermostatic coil to sense underhood temperature and engage the cooling fan only when needed. At higher speeds when less cooling is required, the clutch disengages the fan, reducing parasitic engine load and improving fuel efficiency. The heavy-duty design ensures durability under demanding operating conditions.

Key Features:

• Heavy-duty thermal fan clutch design meets or exceeds OEM specifications
• CNC-machined aluminum body for precision fitment and efficient heat dissipation
• High-quality, high-load bearing packed with high-temperature moly grease for extended service life
• Clockwise rotation — bolt-on installation
• Thermostatic engagement engages fan at low speeds when cooling is needed; disengages at high speeds to reduce engine load
• Includes fan mounting hardware
• General application coverage with clutch specifications printed on stock number label

The Caliso 22045 thermal fan clutch is a dependable, direct-fit replacement for a broad range of classic and late-model domestic vehicles, making it an ideal solution for restoring proper engine cooling performance.
